Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Intestinal Parasites of Juvenile Salmonids from the Lower Oder River Basin and from the Middle of the Neman River
No full textAtlantic salmon died out in Poland during the 1980s. The current population was recreated with Latvian salmon and now forms part of the southern Baltic cohort. Polish sea trout and brown trout come from the home cohort, but have survived only with regular restocking. In Lithuania, all the salmonides are from the home cohort and have not been restocked. The aim of this study was to compare parasitic invasion in juvenile salmonides that come from Poland and Lithuania. The juvenile salmonides in this study came from the lower Oder River basin and from the middle of the Neman River. 153 fish were caught using electrofishing from 2004 to 2006. The salmonides in the Oder had been artificially restocked and those in the Neman were wild. 33 salmon, 58 sea trout and 24 brown trout came from small tributaries of the Oder; 22 salmon, 5 sea trout and 11 brown trout came from tributaries of the middle Neman River. The fish were either 0+, 1+, or 2+ years old. Their size was characteristic for their species at that age, which suggested that they were in good condition. Our examination found 6 species of parasites from 3 taxa: Cestoda – Cyathocephalus truncates; Nematoda – Cystidicoloides ephe¬meridarum and Raphidascaris acus; and Acanthocephala – Acantho¬cephalus lucii, A. anguillae and Metechinorhynchus truttae. We found all three taxa of parasites in all the salmonides that came from the tributaries of the Oder, but all three taxa were found only in salmon from the Neman tributaries. In sea trout and brown trout from tributaries of the Nemen River we found only Nematoda. The invasion frequency was much higher in salmonides that came from tributaries of the Oder River than in salmonides from tributaries of the Nemen River. In tributaries of the Oder River, 57.6% of the salmon, 62.1% of the sea trout, and 58.3% of the brown trout had parasites. In tributaries of the Nemen River, 27.3% of the salmon, 40% of the sea trout, and 36.4% of the brown trout had parasites. In salmonides from both rivers the most common parasites were C. ephemeridarum, M. truttae, and C. truncatus. The other species of parasites were found in very few cases. Older salmonides had greater numbers of parasites. Although the salmonides came from different rivers and had different origins, the species of parasites that they had were typical for their family. In conclusion, parasite invasion is similar in salmonides both from the lower Oder River basin and from the middle of the Neman River
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Radon Surveys In Brazil Using Cr-39
No full textIn this work results of two radon daughters survey in Brazil are presented and discussed. Some methodological problems concerning the first survey are pointed out which were corrected for the second survey in order to make a realistic long-term measurement of radon decay products in the air. The technique employed in both surveys was the alpha-spectroscopy using CR-39. The reliability of this technique as well as the results of the second survey are discussed, which indicate a poor correlation between radon and its decay products in the air at the researched dwellings. © 2005 Elsevier Ltd.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Indoor Radon And Radon Progeny Survey At Campinas-brazil Using Cr-39: Final Results
No full textIn a survey performed at Campinas-SP, Brazil, the CR-39 detector was used as an alpha-spectrometer taking into account the size and the gray level of round tracks measured under an automatic optical microscopy system. The exposures were carried out in the same room of 70 dwellings during two successive periods of six months: the first one from November 1996 to May 1997 (summer exposure) and the second one from May 1997 to December 1997 (winter exposure). The results of the assessment of radon and radon progeny (RP) joint activity in the air neighboring the detector and the plated-out RP activity on the material surfaces are given. © 2008 Elsevier Ltd.
